Chemotherapy uses chemical drugs to kill tumor cells and treats the entire body, whereas radiotherapy uses ionizing radiation to destroy tumor cells and targets only the localized area. Both chemotherapy and radiotherapy are used to treat malignant tumors. During treatment, patients should ensure adequate rest, avoid excessive mental stress, maintain a positive and cheerful mood, and consume more fresh fruits.
